" MEANS FOR OPENING AND CLOSING CARRIAGE-WINDOWS provements in means foropening and closing carriage windows, in which the window is moved bymeans of a chain gear.

The improvements refer more particularly to the Working of the chainpinion and the locking arrangement for securing the latter in position,and further the formation of the plate to be attached to the window, orthe cam arrangement provided on the chain, and lastly, the formation ofthe chain-pinion.

Referring to the drawings which form a part of this specification itshows an arrangement for opening and closing carriage windows, embodyingthe present improvement in which,

Figure 1-is an elevation, Fig. 2 a vertical cross section of thearrangement, Figs. 3 and 4 respectively front and back views of'thechain pinion-j Fig. 5 a vertical section of the latter, with the lockinga'rrangement'for securing the apparatus in position, Figs. 6 and 7 aredetails and Fig. 8 shows an alternative form of the pinion, Fig. 9 showsa section of an alternative form of the'locking device for securing thepinion, and Figs. 10 and 11 are respectively a back view and crosssection of the latter. Figs. 12 to 14 show, respectively,

a front elevation, cross section and plan of another form of theconnecting or cam plate to be attached to the carriage window.

The arrangement illustrated shows, a known arrangement comprising twochainwheels 2 and 3,.connected by a chain 1, and

which are supported in the side of the carriage 4, which at the sametime is designed to receive the lowered window. The chainwheels areprovided with teeth arranged in arallel pairs 5, Figs. 3, 1, 5,. 9,11,between which the links 6 ofthe chain formed of thin plate, set onedge, can lodge whereby the chain is more efficiently borne and ided.The upper chain-wheel 2 1s driven irect by turning the handle], which isslid over the'pin or spindle 8, Figs?) and 9.

Specification of Letters Patent.

In Fig. 5, the chain pinion 2 is firmly j oincd to a box 9, which canrevolve in the bearing plate 10 and is provided on its front .face withtwo projections or shoulders 11, placed diametrically opposite eachother,

ing arms 12, of the pin 8, are made to bear 5 when the handle 7 isturned, so that the 5 chain pinion is made to revolve with the ahaudle.Butbefore this can be done .the chain pinion must be released, bydisengaging the locking arrangement which secures the chain pinion inposition in the known 1 manner. This locking arrangement consists of-abolting device 13, loosely slid over the pin 8, and which by means oftwo projections .14: (Figs. 5 and 6) protruding through recesses in thebearing plate 10, catches into suitable notches 15 in the chain pinion(Fig. 4). F or the purpose of bringing the locking arrangement intoaction the box 9 carrying the chain pinion is provided, onthe sidefacing toward the extensions or arms '12 of the pin. on either side ofthe projections 11 (Fig. 7i two slide-faces 1(5 ascending toward thelatter projections, and against which the arms 12 of the pin areconstantly pressed, by a spring 17 inserted in the box 9. When the pinis turned,its arms 12 ride on the slanting faces 16 and thus push thepin forward, so that the bolting device 13 is also pushed forward andits projections are disengaged from the notches of the pinion, so thatwhen the pin 8 is turned farther, the pinion will be made to revolvewith the pin by the arms 12 of the pin bearing against the shoulders orprojections 11 .ot' the pinion. As soon as the handle 7 is released thepinion is locked again in position, by means of the spring 17 whichforces the pin 8 backward, and at the same time the bolting device isalso carried back, by a shoulder 18 on the pin, until it catches intothe notches of the pinion. At the same time the pin is made to revolve,by its arms 12 riding on the slanting faces 16, so'that itis broughtback again into the position shown in Fig. 7-, in which the arms 12 arehalf-way between the 7 isonce more turned the. bolting device is in thefirst place released, and thereafter the pinion is set in motion.

According to Figs. 9 to 11, the chain pinvolve in a boxjlO'belonging tothe hearing and against which two oppositely project ion 2, with itsnave 8, is borne so as to rctwo projections 11, so that, when the handleI ranged on the back of the pinion 2 itself.

The bolting device 13 the farther end of the pin 8 and engages by meansof its locking pins 14', (protruding through two holes 15 in the pinion2,) the notches 10 of the bearing 10. The spring 17, which presses thearms 12 of the pin 8 against the slide faces 16 is arranged between thenave 8- of the pinion and the handle 7, both nave and pinion beingsuitably recessed. lVhen the pin 8 is turned, its arms 12 ride on theinclined faces 16, cans ing the pin 8 to be displaced longitudinally,

is fitted loosely upon backward, while at the same time the boltdisplaced backward,

arrangement 13 is also and its locking pins 14: are disengaged from thenotches 10 of the bearing box 10, so that, when the pin 8 is turnedfarther and its arms 12 are made to bear against the projections orshoulders 11, the pinion 2 is made to revolve. As soon as the handle 7is released the pinion 2 is locked again by the spring 17, essentiallyin the same Way as in the locking arrangement first described.

The moving of the window is effected in the known manner by means of thecam proection 19 on the chain 1, wlnch catches into the connecting plateor cam plate 20 attached to the carriage window. This plate 20 isattached to the window, by means of a second connecting plate 21 (Figs.2 and 18). These two connecting plates are arranged displaceably so thatthey can be adjusted and fixed in the desired position relatively toeach other, so that the connecting plate acted upon by the projection onthe chain can be adjusted at will even when attached to the window.

The beveled shoulder 22 and the stop or catch 23 of the chain 1 serve,in the known manner, to press the window, when raised, against theweather-rail, and, respectively to limit the lift of the *indow, whilethe catch or-stop 23 strikes when in the corresponding position, againstpins 24 arranged on the bearing plates of the two chain-wheels.

For heavy windows, the driving wheel fitted with double teeth, (Fig. 8)is provided, in the known manner, with an inside gearing 26-, into whichthe pinion 25 gears, which is otherwise constructed as shown in Figs. 5or 9. The pressing of the raised window against the weather rail canalso be face of the fillet, by

attained by a peculiar form,

ing provided, a ong its giving the connecting late 20 guiding edge whichis acted upon by the against which a projection or shoulder 28 ofprojection 19 bears when the Window is raised, thus pressingthe'connecting plate, and the window outward the window over the weatherrail. The window will thenremain' in this position until the projection28, in the course of its travel, reaches the other end of the fillet 27,when the window, already lowered a little, is again forced inward, alongthe beveled sura pressure spring 29. of the usual kind.

Having now described my invention, what I claim as new and'desire tosecure by Letters Patent is:

1. In a device for movin carriage windows with chain gear, a chainpinion'having on one face shoulders (11, 11) and slanting surfaces (16,16') on both sides of said shoulders ascending toward the same, aspindle (8) adjustable longitudinally and adapted to rotate the chainpinion, said pinion being provided at its inner end with perpendiculararms (12, 12), a coiled spring (17, 17 surrounding the inner end of theand thus forcing 1 spindle and adapted to press the said spindle arms(12, 12) against the said slanting surfaces of the chain pinion, abolting arrangement (13, 13), rotatably seated upon the.

spindle and having projections (14,14'), in combination with notches-0nthe chain pinion adapted to receive the projections 2. In a device forfastening and moving carriage windows, a chain drive, a projection (19)fixed to said drive, a plate (20) fastened to the window and providedwith a guiding curve for the said projection, said' plate having alongthe guiding curve a hearing fillet (27), in combination with a shout?-der (28) on saidprojection adapted to en-' gage the bearing fillet,substantially as set forth.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
